Chapter 3See details

Incident Reporting and Investigation

  • Lesson 1 • Root Cause Analysis Methods

    Applies five-whys, fishbone diagrams, and fault tree analysis to uncover systemic causes. Moves investigation beyond surface symptoms to organizational and systemic factors.

  • Lesson 2 • Scene Preservation and Evidence Collection

    Covers immediate response steps, scene security, and evidence documentation methods. Protects investigation integrity and supports accurate causal analysis.

  • Lesson 3 • Investigation Reporting and Communication

    Structures investigation reports for technical and executive audiences. Ensures findings drive organizational learning rather than blame assignment.

  • Lesson 4 • Corrective and Preventive Actions

    Designs SMART corrective actions, assigns ownership, and tracks closure. Links investigation findings directly to risk assessment updates and management system improvements.

  • Lesson 5 • Incident Classification and Reporting

    Defines severity categories from near-miss to fatality and maps reporting timelines. Establishes accurate classification as the foundation for meaningful trend analysis.

Chapter 4See details

Occupational Health and Hygiene

  • Lesson 1 • Biological and Ergonomic Hazards

    Identifies pathogen transmission routes and musculoskeletal disorder risk factors. Applies workstation design and infection control measures to reduce health impacts.

  • Lesson 2 • Physical Agents: Noise and Vibration

    Quantifies noise dose, vibration exposure, and associated health effects. Applies engineering and administrative controls to reduce worker exposure below harm thresholds.

  • Lesson 3 • Occupational Exposure Limits and Monitoring

    Explains time-weighted averages, short-term exposure limits, and ceiling values. Connects exposure standards to sampling strategies and instrument selection.

  • Lesson 4 • Chemical Hazard Management

    Covers safety data sheet interpretation, chemical inventory control, and substitution strategies. Builds competency in communicating chemical hazards through labeling systems.

  • Lesson 5 • Health Surveillance and Fitness for Work

    Designs health surveillance programs linked to specific exposure profiles. Addresses fitness-for-work assessments and return-to-work planning after illness or injury.

Chapter 5See details
